'.To, all whom 'it may concern:

13e it known that I, MAJOR F. SKIDMORE, afitizen of the' United States,residing at Toledo, in the county of Lucas and State 0f Ohio, haveinvented a new and useful 'Fountain-Pen, of which the following is aspecification.

. My invention relates toa fountain pen of the kind having a collapsibleink reservoir housed within its stem and has for its object to providemeans to more evenly collapse said reservoir initiatively to its fillingand soy arrange the compression means that the same may be readilyhoused within the stem without undue encroachment upon the spaceallotted to the reservoir and in'such a juxtaposition thereto, thatwithout injury to its walls, v said reservoir may be collapsed forfilling for a greater portion of its length as well as of its girth.

The objects of my invention are accomplished as, hereinafter describedand illustrated in the drawings in which- Figure 1, is a view partly insectlon 'of a fountain pen const-ructed in accordance with my inventionand showing the normal posi.-

tion of my compression means and the reservoir` in full. Fig. 2, vis alike View but showing the mechanism in the position in which thereservoir is collapsed.v Fig. 3, is

' an isometric view of my compression meehanism. Fig. 4, is asectiont-hrough the pivotal joint, and Fig. 5, is a view showing amethod of attaching the pressure plate to the rocker bar. Fig. 6, is anend view of the barrel showing the reduced nipple and the slot for thepressure-lever.

The fountain pen illustrated in the drawings is of usual form and itshead (1) is formed to socketand support a pen 2, being-also providedwith a supply tube and opposite to the pen and the supply tube, saidhead is diametrically reduced to form .a shoulder odset 4 and againreduced 1n d1- 'ameter to form a nipple portion 5 upon which a sack 5vfor the ink, or a reservoir of collapsible material is mounted.' Theshoulder offset 4 is' of a size to forcibly' telescope into the bore 6of a barrel orI lstem 7 which has its opposite end closed by a head.

8. The head 8 is provided with a'threaded extension 8 of a reduceddiameter. The barrel 7 is of a v length to house the lnksack within itsbore and to compress said sack for iilling, I have provided a pressureplate 10 which is of a length to extend from near the nipple to the freeend of the sack, and as a means to bear the plate upon the sack I havecoupled the head end 10 of the plate to the free arms 11 of a lever 12which are so angled near the head 8 that short arms 13 are formed whichare of a:

length slightly less than the diameter of the bore 6' being connected bymeans of an integral bight 14. The long arms 16 and the short arms 13 ofthe lever' 12 and the con is provided with an end bore 16 in which ispressed a stem 17 the free end of which is upset to form a head 18. Thepressure lever 19 is pivoted to this head and extends therefrom betweenthe arms ll/through the slot 20 a suitable dist-ance outward from thehead 8 andis provided with a terminal knot 21. To impart motion to thearms 11, said pressure lever is coupled to the arms about .midway oftheir length by a pivot 22 com mon to the arms and to the lever. By theplate, angled lever and bar thus arranged and housed within the bore ofthe stem 7 collapsing pressure may be brought to bear upon the ink sackby pressing upon free end of the lever 19 which results in rocking ofthe angled lever 12 and depresses the free end upon the ink sack, whilethe free end of the pressure plate is brought to bear upon the ink sackby the pressure directly imparted by the lever 19 to collapse the headand the pressure bar being made ,of

spring wire which is flexed to collapse the reservoir will return theparts to their normal position when pressure upon the lever 19 isreleased, with the result that the ink sack is lilled'by externalpressure. The free end of t-he lever 19 is protected by means of cap 23which is threaded to the extensionv such purpos e is telescoped upon theheadend 8.

What I claim is,

l. A fountain pen, having a tubular stem and a compressible ink-sack; apressure plate, a leverl adapted to roel: within the cavity of thetubular stein and having `its inner end coupled to the inner end of thepressure-plate, and a spring operating lever, fixed to the head end ofthe stem, and pivotally connected to rock leverj adapted to impart withthe rock-lever a parallel compressing motion to the pressurev plate.

2. A fountain pen, having a tubular stein and a. housed in ink-sack,compressing means for saidinksack, comprising a pressure-plate, anangled lever, havingthe end of its long arm fixed to the end of thepressure-plate adjacent the nipple for the inksack, and its short yarmadapted to rock upon the Wall of the stem, a spring pressure bar,extended from the nipple, being pivotallyeonneeted to the long arm ofthe angle levell about midway of its length, and

ladapted to bearL upon the free nd of the pressure-plate. l

3. A fountain pen, having an lnk-sack housed Within a built-up tubularstem; compressing means for the .ink-sack, comprising f a;pressure-plate, lever arms Coupledl to the .the long arms of the angledlevers about mid-Way oi" their length, and adapted to bear upon the freeend of the pressureplate, and a slot in the stern for the extensin ofthe spring pressure-,bar and permitting its movement across the area ofthe stem. I

In Witness whereof, l have hereunto set my hand this l0 day of May1909..-2'
